Description Jim McDonough 2009-12-09 11:08:43 UTC
A fatal error occurs if ctdbd is started with non-zero priority.  sched_setschedule() cannot be called with SCHED_OTHER and a non-zero priority.
This was first discovered at 1.0.89 but is still there.

To reproduce, just start with:
chrt -r 1 /etc/init.d/ctdb start

A patch will be attached.

As ctdb no longer uses sched_setschedule(), this can be closed
